Pro Desk Briefcase

ABSTRACT

An advanced Briefcase that converts into a desk via retractable leg and a front, left, and right side walls of the briefcase that folds down to create a desk top surface. This surface can also expand out to create a larger desk top surface. It also has a PORTABLE USB charging station and a cup holder. The portable briefcase will be designed comparable to most Briefcase but will separate it&#39;s self from all Briefcases as it can turn into a work desk. Prior designs of Briefcase stopped at being a housing unit for paper work and supplies where mine has advanced the Briefcase by adding adjustable legs on all sides of the bottom of the Briefcase to enable the Briefcase to be used as a work desk and the ability for the front and both sides of the briefcase to fold down to create a desk top surface that can be extended out to create a larger desk to surface along with being a housing unit for paper work and supplies.

FIELD OF THE INVENTION

A briefcase that converts into a potable desk via extended and ajustable legs housed in the briefcase and a desk top that folds down to creat a desk top and can be extended out to create a larger desk top surface.

BACKGROUND OF THE INVENTION

Professionals have long used briefcases to house their paperwork and important documents however briefcase have been limited in their usage to simply being a carrying case for documents whereas now a briefcase can transform into a workable desk where professionals can do their work in court building waiting room sitting on a benches, sitting on a park bench, on the subway or at a coffee shop.
